"Crowding of dairy cows housed in cubicles was not scientifically described or categorized at leastin available literature. However, when it is about space allowance and density there are number of researches. The aim of this study was to categorize crowding of dairy cows and to give answer about its duration throughout the year, but also to provide milk production characteristic before and during the crowding period. Cows were housed in cubicles. For the aim of this study we calculated the differences between daily milk yields of June 1, compared to July 1, August 1, September 1 and October 1. Cows were divided by the stage of lactation on 3 groups (first: cows on II, second: cows on III and third: cows on IV lactation + higher lact. up to 7th), with 32.7+-10 cows in each. In the beginning of experiment (June 1) 55% of cows were up to 100 days of lactation, 31% from 100 -- 200 days and 14% >200 days. The cows were monitored with two outdoor network cameras (VIVOTEK technology, IP7330 and PZ6122) from July 2 (approximately 10 days before crowding started) to October 15 (7 days after crowding stop), total of 106 days. We take the snapshots at 14 p.m., because was found that in this period of the day, the crowding if there it is any is always present. To assess the severity of crowding behavior and its characteristics, we developed a scale based to available space per cow and usage of it. We found that in period from July 2, to October 15, 2009 were 84 days when cows were crowded. First crowding was determined at July 11. After that, crowding was almost permanently present until October 8, with shorter breaks. There was found an evident drop in daily mil production after crowding started. Crowding phenomena strongly affects cow's behaviour in one part of the day during summer period. Crowding of dairy cows could contribute to decreasing of milk production and negatively affect comfort of cows." . "Categorization of crowding behaviour in dairy cows during summer period" . .
